n I will tdescrlbe the apparatus in which the re lationL of combustion is `eiiected manna yLSThe heater `proper 1 has an enlarged outer'chamber` and a reduced inner chamber orpassage 2 arranged horizontally and suitably connected with a flue. A vertlcal ipe Sextends upward from the body 1 of t e heater 'and upon it is .supported an 'gauze 51 (Fig..4),"constituting a -oil-holder` proper 4. The latter las transverse, vertical, parallel portions 5, which are rovided with openings spaced',v a' art and near the v ottoni which are covered a wirev ter-.for the oil; and`6xis a needle valve, whose stem extends upwardthrough the centralportion 7 of the vtop of ,-the"\oil-holder 4, and 1s there` connected. witha lever Sthat is fulcrfum'ed adjustablyon a short post 9.4 `The outer end of the 'lever 1s jointed'at` 8f yto a vertical rod y 10 which medew-threaded .-at11,where a' vhand-nutv 12 l is `a liedfthe'` resting upon a disk 13 z whic in lturnsupported on `the tube 3.

is appliedto the `rod 10 below the disk 13, and tends to draw the latter downward and thereby open the valves. By adjusting this nut 12, vit is obvious that the rod 10 may be raised or lowered, and thereby, through the medium ofthe lever 8, the needle valve 6 will be correspondinglyadjusted, so as to allow a greater or less'iiow of liquid from lthe holder `4. v

` Let it be supposed that the holder is lilledy with crude oil, and the needle valve 6 raised more or,` less, Ithe oil will flow down over a cone 6a which is fixed on the lower end `of the needle valve in the upper portion of the tube 3.` Oil drips from the base of this cone and falls upon a of plates 14, which, in view of their function, 4may be termed dampers. The same are bent at an obtuse angle and pivoted at14, so asI to lie, generally speaking, in horizontal planes. Their right-hand ends are pivoted to the lower portion or section of a rod 15, by which they may be adjusted, andsaid rod is in turn connected, by an adjustable joint- '16, with the aforesaid rod 10 that governs the position o the needle valve 6. 'It is obvious that the connection between the Shanks or` stemsV of the dam ers must be -such as to permit vibration o the dampers when therrod is moved vertically.. For this purpose, the opening in theshanks of the amper may be elongated, or formed as a slot, as shown in Fig. 1. i The dampers 14 are made successively longerl from the top downward and their obtuse-angle free ends thus overlap each other in the manner of shingles on a roof. The oil dripping u on broken up .mechanically, and air supplied fromk the rear mingles with the heated and gasili'ed oil,` which being 'i out through the passage 2.` The air to be supplied is heated in its passage, since it lpasses through a grated opening 17, thence t j ited, is con-l sumed, the products of 4com ustionpassmg 'loo rough a assage 18 "lyingybelow the combustion C amb inhrearfof' thedampers'14.` Figs. 7 v'and 8 `serve. to illustrate, diagrammatically, 'andl somewhat crudely, thejeffect produced by. `the dropping of 011 on the downwardly inclined ends ofthe dampersl4, whenthe same varenearly closed and' when opened to aiconsiderable extent. In Fig. "I, theyy are `roper,and then rupward'into a chamber 19- P 6 and the dampers 14, is such that, when one is opened widely, the others are also; and vice versa. Thus the supply of air to support combustion is always proportionate to the amount of oil delivered upon the dampers.

Alongside the needle valve 6, I arrange a supplemental hand-operated needle valve which is so adjusted as to allow a small,` but constant, drip of oil upon the central dampers whose free ends are provided with slots or openings as shown. The oil thus alsv -ment by a screw 25.

delivered serves to support a pilot flame or light, so that if. the supply ot oil by the needle valve 6 be entirely cut ott, ignition will again occur when the needle valve is reopened.

The combustion chamber, at a point 21 directly below the dampers 14, is depressed, as shown, and a tube 22 is attached at that point and serves to conduct into a receiver 23 any foil which may fail of combustion inthe chamber.

. The upper portion or section of the tube 3y ismade-of glass, or else provided with a glazed inspection opening, so that it may be ascertained, at any time, what amount of oil is discharging from the cone 6a.

The fulcrum post 9 of lever 8 may be adjusted right or left on the top 7 of the oilholder, and may be clamped in any adjust- As previously intimated, 7 indicates the middle ortion of the oil-holder, or that portion which covers the space between the two parallel partitions. Separate removablecovers 7a (see Fig.y 3) which are semi-circular in form, are applied tocover the Side portions or compartment-s of thecoil-holder. j

A pipe 26, made in sections, connects the upperjportion of the oil-holder with the tcombustion chamber 2, and serves to conduct' Afrom theformerto the latter any gas or oil vapor which may be formed in the holder.

The lower portion-of the oil-drip tube 3 issurrounded by a water-holder 27. The watercools the. pipe' to a certain degree and lthus yhinders the-vaporization or gasification vof the/oil therein, while warm vwater is at the, lsame timel provided for domestic or othelvusxe.k `The, dampers are arranged in what may be termed a housing 14 the same being adapted toit the interior of the combustlonchamberand lthe forward edge being inclined and abuttingA ribs 1d formed on the 'sides `of the chamber. l,The housin with the,A dampers..- adatached, may be easi y adlustedin place-0r, removed. I

The body 1 of the heater is provided at 1d with a vertical flange which is in contact with the wall of the iiue and assists in closing the opening therein. The outer portion of the heater 1 is supported by legs 1b which may be secured in'any required adjustment by clamp-screws 1, as shown in Fig. 2.

In Fig. 2, I show an automatic thermostatic regulator which may be used in place of the hand regulator shown in Fig. l. Thus, a bowed or U-.shape spring 28 is arranged in horizontal position, one end being connected with the rod 10, and the other with a tube which is adjusted by a screw and bears upon a spiral spring 30 and is arranged for vertical a justment in a bracket 3l. By rotating this screw, it is obvious that the longer arm of the spring 28 may be adjustedhigher or lower and its tension thereby increased. The spring 28 is made of different metals such as are ordinarily employed for producing a thermostatic action for example of steel and copper. The top of the bracket 3, is circular or disk-like as shown in Fig. 6 and is graduated and bears different numerals for indicating different adjustments of the screw 29, the latter having an index or pointer which sweeps over the graduated disk.

It will be apparent that the spring 28 will expand or contract more or less according to the temperature of the air surrounding it, or the heat radiating from the heater, and that thereby the rod 10a will be adjusted higher or lower, with the corresponding ei'i'eet of opening or closing the needle valve 6 and the dampers 14 more or less.

What I claim is:

1. The combination of an oil-holder, a heater body located below, and a tube connecting the same, a needle valve applied to thel oil-holder, a series of dampers arranged in the body of the heater, and pivoted so that Atheir free ends may be adjusted nearer or farther apart, and a rod connecting their rear ends with the valve, and means for adjusting the rod higher orlower so that the valve and dampers in the heater may be opened simultaneously' more or less, substantially as described.

2. The combination of a heater bod and an oil-holder having a valve for regu ating discharge of oil therefrom and provided at its lower end with a cone from which the oil drips, dampers arranged in the heater and in position to receive the drip, -and means for connecting them with the said valve so that both are adjusted simultaneously, substantially as described.v

3. The combination of a heater proper having a combustion chamber, and an oilholder provided with a valve governing dis.- charge of oil therefrom, and means for regulating accessl of air to said combustion chamber, such means being connected with the aforesaid valve so that both are adjusted simultaneously, substantially as described.

4. The combination with an oil-holder and a valve for regulating the discharge therefrom, of a supplemental valve for regulating drip to support an igniting flame, a chambered heater body arranged below and provided with dampers pivoted therein and arranged to overlap, whereby they may be opened or closed more or less to govern the admission of air to the chamber of the heater, and one of them provided at its free end'with a slot which permits free passage of air at all times, substantially as described.

5. The combination with a heater body, an oil-holder, and a vertical tube connecting the two, of a needle valve arranged in the holder, a lever connected therewith and hav ing a laterally adjustable fulcrum; dampers arranged inthe heater for governing the passage of air to the same, and a rod connectlng such dampers with the aforesaid lever.
